.To all whom it may con/cern:

Be it known that we, EDWIN T. 'MARBLE and EDWIN H. MARBLE, citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Machine for Waxing Velvets, Plushes, and other Pile Fabrics, of which the following, together with the accompanying drawings, is a specification su-iticiently full,clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The objectof our present invention is to provide in a machine for waxing fabrics a revolving bar-wax carrier and facilities for supporting and adjusting the fabric in proper relation for receiving the wax therefrom in greater or less quantity uniformly upon the Surface of the fabric; also, to provide efficient means for dampening and cooling the wax surfaces in proper degree to obviate the ex,-` cessive softening of the same by friction or by variations of temperature.

Another object is to improve the general construction of the mechanism and to render the machine convenient, efficient, and desirable for use. These objects we attain by mechanism the nature, construction, and operation of whichv is explained in the following description, and illustrated in the drawings, the particular subject-matter claimed being hereinafter definitely specified. Y

In the drawings, Figure 1 is a central longitudinal section at line a: a: (the lower left corner showing the side) of a fabric-waxing machine constructed in accordance with our invention. Fig. 2 is a half-vertical section and half-front view of the same. Fig. 3 shows the adjustable roll-bearing support for the apron.

Our invention comprises a revolving wax-V carrier composed of a series of recessed bars or long radially-hollowed boxes or pockets arranged at the periphery of suitable spiders or wheels,in connection with arotatable shaft or axis arranged to turn in suitable bearings on the supporting-frame and having adriving-pulley or means for imparting rapid rotary motion tothe carrier. Sald recessed bars or boxes form receptacles for containing long iiat bars of wax and are provided with suitable plates and screws or devices for clamping the'bar-wax in place and for adjusting the same outward as the wax wears away by its distribution upon the fabric. lIn combifabric can be strained with a greater or less 6o degree of tension and its surface thus presented to the revolving carrier, while the fabric is fed forward with a constant movement.

IOur invention also comprises means for quickly relieving the fabric from the waxing action and for varying the fabric tension and the quantity of wax applied to the pile-surface thereof.

Our invention .further comprises, in combination with the wax-carrier, an improved cool- 7o ing and dampening apparatus havingaexible traveling apron that is Vsuspended ina manner to properly wipe the edge o'f the wax bars as the carrier revolves, the said apparatus being provided with adjustable bearings for the apron-supporting rolls to afford greater or less pressure in its action on the Wax, also with facilities for advancing this cooling-apron at required speed.

Minor features ofim'provement will be noted 8o in explaining the construction of our invention, which we will 'now proceedY to describe more in detail. A

In the drawings, A denotes the frame; B,

the feed-roller covered with card-clothing; C, 85

Ythe wax-carrier composed of the spiders or end wheels C', fixed 'on the shaft C2 and having t-he wax-carrying bars or boxes c, rigidly attached to the peripheries of said wheels, as

indicated. In the present instance fiveof said 9o bars are employed, but more or less in number can be used, as :in any instance desired. The shaft C2 is provided at one end with pulleys C3 for the driving-belt and at the other end with pulleys a and b for operating the brush and feeding-roll mechanism, `the' belts and gearing for which are not herein shown, but may be of any suitable kind for transmitting the motion and power to the parts operated thereby.

D indicates the pieces of wax material, which are best formed in long flat bars of rect- TOO ` frf I angular section about one and one-eighth inch (more or less) in thickness `and of any desired Width adapted to set into the recess of the carrier-bar c flatwise or so as to project therefrom radially and presentits edge to the work. The bar of Wax D is securely held within the carrierpocket `bya plate land set-z screws@ at one side thereof, andan edge-.plate d and setsercws e are provided for adjusting and supporting the bar-wax with thel l proper amount of projection at the periphery` F indicates a movable frame or fabric-sup-` porter pivoted at f to a stationary part and adapted tnswing toward and ifrom the wait` carrier. A card-toothed `holdbaclc-roll G is journaled in bearings on the side bars at the front part of `said supporter and a guide bar or roll "F2 is disposed parallel therewith in bearings or ears near the rearpart of said sup-` porter, said rolls G and F2 being about equi-` distant from aplaneperpendieulartothesupporter andpassing through the axis of the carrier C. A friction-brake g, having a binding-sere1 `or means for adjusting thepressure of the same, is provided `for controlling the resistantaction of the holdback-roll G, and thereby regulating the tension on thefabrio, Which is spread and strained taut across the space from the roll G toihe roll F2 and its surface there `presentedfto the action of the waxbars,Whichstrike the rlexiblepartof the fabric midway between the said rolls.

'H indicates a shaft having carns7L,Wl1ereon the swinging end of the fabric-supporterF is sustained and 'by means of which the same can be adjusted nearer to or farther from the Wax-carrier. A hand-Wheel ll is arranged on the outer end of said shaft to facilitate rotation of the cams, and a `ratchet-wheel h2 and pawl hcarejprovided for-locking the shaft and `cams atposition of adjustment. A stop-iingerisbest arranged on the cam-shaft Vto engage with alug fixed on the frame, as atj, to `prevent rotation of the cams beyond :.illeir normal limit of action.

J Jindicate guiding-rolls for directing the` fabric,the course over which the fabric trav, els through the machine being indicated inl Fig. l by the dash-and-dot lineVV.

K indicates the coolingapron, `Whichis ar-` ranged above the Wax-carrierand mounted upon guiding-rolls K K', by which it is sus-` pended `at a position where the edges of `thel waXD will come into contact Withits extended, central ,part as the wax-carrier revolves, sol that the apron Wipes and cools 'the rubbingedge of the wax and prevents the softening ofthe samefrom heat caused by friction on thepile of the fabric or by atmospheric temperature. The bearings i of the rolls K` are `jpivoted or adjustably attached to the main frame, so that the rolls K can be depressed or elevatedto cause the apron to bear with greater o1" less force or fora longer interval upon the wax bars D. A take-up roll K2, mounted in adjustable bearings k, is arranged within the apron for increasing or diminishin g the tension thereof, as desired. For dampening, the apron passes between two rolls--a drive-roll L and presser-roll Lmounted in bearings at the top of the frame, and said drive-rell runs in a trough M, containing water or other dampening material. The driveroll L `isoperated by a belt n on its pulley Z from the intermediate pulleys or change wheel m, running on a stud or axis near the lower part of the frame, which pulley is in turn actuated by a belt n from a pulley fm2 on the wax-carrier shaft'C2. Hence a continuous advance motion is imparted to the apron lKffrom the carrier at aspeed which can be Mproportionally varied by varying the sizes of the intermediate or change Wheels m, as required.

P indicates the revolving brush for Working the wax into the pile-of the fabric, and O the bed-roll for supporting the fabric adjacent to the brush. swinging bearing-arms r, connected Witha rocker-shaft R and a toothed segment `and worin-screw v", and a hand-Wheel Rzlis provided for adjusting said roll O .toward or vfrom the brush to give greater orlesseffective action on the fabric or to accommodate fabrics having different depths of pile.

'l indicates a swinging tailguide to `discharge the fabric in folds.

In the operation the fabricis drawn through the machine `in the `direction indicated and the Wax-carrier is revolved,bringingthemvax bars D successively into contact with the `pile on that part of the fabric which is flexibly sustained by being drawn taut between the holdbaclc-roll G and supporter-bar F2, and Wax is thus laid upon the face of the fabric in a very uniform, efficient, and desirable manner, the quantity deposited being varied, as desired, by adjusting the supporterF by aid of the cam-shaft and cams 7L nearer lo and farther from the Wax-carrier.

By our invention We provide a machine that can be practically operated at much higher degree of` speed than can be successfully done Wi th machines as heretofore constructed,\vliile the mechanism is more conveniently and effectively adapted to the requirements ofthe Work and by it the Wax can be uniformly and satisfactorily laid upon the pile in heavy or light quantity, as may in any instancebede- Sired.

It will be understood that we do not broadly claim a rotatable waxing mechanism irrespective of construction, as We are aware that `revolving cylinders of wax have heretofore been employed, but of different construction from our improved mechanism. "Neither do We broadly claim the use of an endlessdam pening-apron in a Waxing-machine otherwise `than in the improved arrangement and coinbination as hereindescribed.
